2 Claims.

This invention relates to hinges, and more particularly to those fordoors or the like.

Generally stated, the object of the invention is to provide a novel andimproved construction and arrangement whereby two metal hinge plates,provided with a pintle connection between them, are of such characterthat the two plates are not separable, but are permanently hinged orpivotally connected together.

It is also an object to provide a novel and improved construction andarrangement whereby two hinge plates, although having a knuckle andpintle connection between them, are of such character that one plate iswithout any knuckle, so that the construction is simple andcomparatively inexpensive.

Another object is to provide an improved construction and arrangementwhereby a pintle connection is provided between two hinge plates, but ofsuch character that the pintle is not separable or removable, beingpermanently fastened to one of the plates.

It is also an object to provide certain details and features ofconstruction and combinations tending to increase the general efficiencyand desirability of a hinge of this particular character.

To the foregoing and other useful ends, the invention consists inmatters hereinafter set forth and claimed and shown in the accompanyingdrawing, in which- Fig. 1 is a front elevation of a hinge embodying theprinciples of the invention, showing the same fastened in position tosupport a door.

Fig. 2 is a horizontal section on line 2-2 in Fig. l of the drawing.

Fig. 3 is an enlarged vertical section on line 3-3 in Fig. 1 of thedrawing.

Fig. 4 is a perspective of the parts of the hinge in separatedcondition.

Fig. 5 is a rear elevation of the hinge shown in Fig. 1 of the drawing,with a portion thereof shown broken away for convenience ofillustration.

As thus illustrated, the invention comprises a fiat hinge plate I,having screw holes 2 near the ends thereof, and having a centralvertically disposed opening 3 in the middle portion thereof.

The fiat hinge plate 4 has screw openings 5 and a cylindrical knuckle 6,which latter is adapted to receive the upper and lower pintles I and 8when the hinge is assembled.

As shown more clearly in Figs. 3 and 5, it will be seen that theenlarged heads of the pintle sections I and 8 are spot-welded to theplate I, at 9 and 9, and that the pintle heads are flattened on theirrear sides for this purpose. In assembling the parts, the two pintlesections I and 8 are inserted in the knuckle 6, and the latter is thenplaced opposite the opening 3, with the 1936, Serial No. 89,876

heads of the pintles in position to be welded to the plate I, in themanner shown. In this way, the two hinge plates are inseparablyconnected together, by a knuckle and pintle connection of such characterthat one plate has no knuckle, and that the pintle is permanentlyfastened to one plate. This results in a strong and simple andinexpensive construction of hinge.

It will be seen, therefore, that it is the act of welding or otherwisepermanently fastening the entire pintle, comprising the sections I and8, to one and the same plate, while the parts are all in assembledrelation, that thereby instantly and permanently connects the two hingeplates together, and whereby only one knuckle is necessary. When thepintle sections are welded to the plate I they are, in effect, integraltherewith. And, as indicated in Fig. l and Fig. 3, the pintle does notrotate. As the heads III are left exposed, they can be and are, asshown, ornamental in form. In use, it will be seen that the plate I isfastened to the support II, which may be a door frame, and. that theplate 4 is fastened to the edge of the door I2 shown in Figs. 1 and 2 ofthe drawing.

With the construction shown and described, therefore, the plate 4 has anattaching portion that extends at right angles to the plane of the plateI, and has a portion extending at right angles to said attaching portionand overlying the plate I, spaced from the latter, but extendingparallel therewith, as shown in Fig. 2 of the drawing. The entirepintle, formed by the two sections I and 8, is thus held stationaryrelative to the plate I with the hinge mounted as shown in the drawing,as the plate 4 rotates about the axis of the hinge, while the plate I isheld fixed in stationary position as shown.

What I claim as my invention is:

1. A hinge comprising a plate formed with a single pintle bearing, asecond plate, two pintle sections inserted toward each other in saidbearing and provided with enlarged heads spaced apart by said bearing,with a fiat inner side for each head, and means permanently fasteningthe inner side of each head fiatwise to the outer side of the secondplate, so that the latter and the first plate are permanently hingeconnected together, and whereby the entire pintle thus formed by the twosections is held against rotation, the second plate having a slottherein to receive the inner side of said bearing.

2. A structure as specified in claim 1, said first plate being movableabout the axis of the hinge,

and said second plate being fixed in stationary position, with said slotunoccupied except by said bearing.
